Shraddha Banglorewala edited at 6:44: 1) Lam suggested that we cut open a fish to determine the differerences between the organs/ body parts of those fish to make a judgment of the quality of water. Advantages of this idea:
Catching the fish will not be too hard
It is reliable way to determine if this water has created a suitable enviornment for the fish in the lake.
Disadvantages of this idea:
This process brings up ethical issues, because we are destroying and taking away the life of the fish.
We haven't learnt anything about human and animal bodies (organ system etc.)
2) We can do the same thing we did at the V-Resort, which is using biological indicies to determine the quality of the water. The indices we would use include
The Pollution Tolerance Index
The Simpsons Diversity Index
EPT richness
Advantages of this idea:
We are already familiar with the process and method (How to use a quadrat, how to do the calculations, how to classify species)
Relatively easy
Possible to complete in the time given
Reliable and quantative method of determining the diversity and quality of the lake.
Disadvantages:
It might be hard to place the quadrat because the water is too deep.
We might not be able to find enough species in the water.
Since we may not be able to take samples from a variety of spots in lakes, the data we collect may not be usable for generalizing to the whole lake.

We have decided to do the 2nd idea, with the species diversity/biological indices.

We can do two things from a Biology perspective.
